BLS started tracking green jobs in 2010, defining them as postions in businesses that produce goods or services that benefit the environment or conserve natural resources. The data also includes jobs where workers are tasked with making their companies more environmentally friendly.

Overall, green jobs make up about 2.4 percent of jobs nationwide. In Vermont green jobs were 4.4 percent of total work, while in Florida they were just 1.9 percent. With more than 300,000 green jobs, California was at the top of the list, followed by New York, Texas, Pennsylvania and Illinois.

In Michigan, where about 80 percent of jobs are in the private sector, construction and manufacturing account for a large share of the environmentally-conscious work.
